“…European carnivore community trophic niche composition and overlap has been shown to be conservative and similar across species. The majority of the community comparisons have addressed the overlap between martens and the red fox, describing their feeding habits as opportunistic, with availability playing a major role in prey selection patterns (Goszczynski 1986, Storch et al 1990, Serrafini and Lovari 1993, Lanszki et al 1999, Padial et al 2002. Our results corroborate the high degree of overlap between these two species found in other Mediterranean areas (Serafini and Lovari 1993).…”

“…Our results also corroborate this increased dietary richness in diet. The red fox, however, has been considered to be one of the most generalist carnivores in Europe (Sweden: Storch et al 1990;Poland: Goszczynski 1974Hungary: Lanszki et al 1999;France: Artois et al 1982;Artois 1989;Italy: Serafini and Lovari 1993) and in Mediterranean habitats, where the red fox has been described as feeding on a large range of prey (Italy: Serafini and Lovari 1993;Spain: Calviño et al 1984, Padial et al 2002. However, our data contradict this pattern, with the red fox being the least generalist of the four species studied, but still with a high plasticity in food habits.…”

Trophic niche partitioning between two native and two exotic carnivores in SW Portugal

Abstract. The introduction of exotic species is one of the most pervasive consequences of the increased human mobility. The most known negative effects are the decrease or extinction of natives. The common-genet, Genetta genetta, and the Egyptian mongoose, Herpestes ichneumon, were introduced in the Iberian Peninsula in the 15th and 19th centuries, respectively. The competitive exclusion principle defines that two ecologically similar species cannot coexist. Thus, some degree of partitioning has to occur in species realized niche, which can occur at the trophic level. To test this hypothesis of partitioning we compared the diet of these two exotic species with that of two native species (stone marten, Martes foina, and red fox, Vulpes vulpes). The results show a high degree of overlap (>45%) between the diets of species similar in their feeding strategies (arboreal and ground feeding). Nonetheless, at the finer scale of prey consumed at the species level some differences are found between the native and exotic species. These results suggest that if coexistence is due to trophic niche partitioning it only occurs at the level of the consumed species. However, coexistence may also be due to a combination of different strategies (home-range size, time and space use) that structured the different realized niches of each species.

These species are generally regarded as generalists and opportunists in their feeding behaviour, although Rosen zweig (1966) concluded that the North American pine marten is a microtine specialist.…”

A long-term study of the winter food niche of the pine marten Martes martes in northern boreal Finland Erkki PULLIAINEN and Paivi OLLINMAKI Pulliainen E. and Ollinmáki P. 1996. A long-term study of the winter food niche of the pine marten Martes martes in northern boreal Finland. Acta Theriologica 41: 337-352.The diet of the pine marten Martes martes (Linnaeus, 1758) was studied during 16 successive winters in an uninhabited area in northern boreal Finland. The results are based on 5677 scats analyzed. The present data support earlier findings that the pine marten is an opportunistic generalist, its most favoured food apparently being small rodents, especially Clethrionomys spp. The significant year-to-year variation in the frequency of occurrence of this favoured prey in the diet of the marten correlated positively with summer trapping numbers for these species. Snow cover decreased the martens' consumption of Microtus spp. but not Clethrionomys spp. or the wood lemming Myopus schisticolor. The first real alternative in the absence of small rodents appeared to be the red squirrel Sciurus vulgaris, and in its absence carcasses of reindeer Rangifer tarandus tarandus and eggs. Other food items included birds, the mountain hare Lepus timidus, the common frog Rana temporaria, berries and mushrooms. There was some evidence that the occurrence of red squirrels in the diet was dependent on the abundance of both squirrels and small rodents. We suggest that in northern boreal Finland martens primarily forage for small rodents, and larger prey, which is less available and more difficult to catch, is captured incidentally.

“…These two methods are among the most common methodologies used to assess habitat selection or habitat use in carnivores, including the red fox (e.g., [12][13][14][15][16]). Contrary to snowtracking, radio-telemetry is invasive because it requires immobilizing and handling the animals.…”

Habitat use and home range size of red foxes in Prince Edward Island (Canada) based on snow-tracking and radio-telemetry data

There is a lack of information regarding the ecology and behaviour of red foxes that can be used to elaborate effective management programs for this species on Prince Edward Island (Canada). The main goal of this study was to provide baseline information on habitat selection and home range size of red foxes on Prince Edward Island. Data were collected from snow-tracking and radio-telemetry sessions conducted in two study sites (including one site within Prince Edward Island National Park). Our results indicated that red foxes selected for roads and human-use areas during both the breeding and the kit-rearing seasons in the park. Outside the park, however, the data failed to conclusively show that foxes have a unique preference for human-use habitats or roads. Forests were selected against in both study sites. Although roads are frequently visited by foxes during the kit-rearing season in the park, each individual fox typically stays in this habitat only for short periods of time (< 15 min). This finding suggests that foraging efficiency along the roads is very high possibly reflecting the abundance of anthropogenic food sources. Overall, we present the largest amount of data on habitat selection ever collected for red foxes in Prince Edward Island, Canada. Our results show that food sources in human-use areas and roads are altering the selection and/or use of habitats of red foxes in some areas of Prince Edward Island.
